Pigtail cable MikroTik ACSMAUFL 15 cm U.FL to SMA female, RF adapter lead

Pigtail MikroTik ACSMAUFL is a 15 cm RF adapter lead with a U.FL connector on one end and an SMA female connector on the other. It is designed to connect devices with compact U.FL antenna sockets to equipment using standard SMA female antennas, providing a short, flexible link for external antennas or test equipment. The cable supports wireless frequencies from 0 to 6 GHz and is intended for use where a reliable short RF connection is required.

Advantages

The ACSMAUFL pigtail offers a compact 15 cm length that minimizes signal loss while providing flexibility for positioning antennas. It combines a U.FL connector for small wireless modules and an SMA female for standard antennas, enabling compatibility between different RF interfaces. The cable is suitable for applications across a wide frequency range (0–6 GHz).

Suitable for

• Connecting WLAN modules and mini PCIe/LTE cards with U.FL sockets to external SMA antennas
• Routers, wireless boards and small form-factor devices requiring short RF leads
• Laboratory testing, RF measurement and antenna replacement where a short adapter cable is needed

Key specifications

• Connectors: U.FL to SMA female
• Length: 0.15 m (15 cm)
• Frequency range: 0–6 GHz
• MPN: ACSMAUFL

How to use

Carefully connect the U.FL end to the device’s U.FL socket by aligning and gently pressing until it clicks; avoid excessive force to prevent connector damage. Attach the SMA female end to the male SMA antenna connector by screwing it on until hand-tight. Use the cable to route the external antenna or test equipment as required, keeping bends gentle to preserve RF performance.

Usage recommendations

Use the pigtail for short connections only; avoid repeated detachment of the U.FL connector to prevent wear. Keep the cable length minimal and avoid sharp bends to maintain signal integrity. Ensure connectors are clean and free of debris before mating.
